Faceted search system and method based on water conservancy object classification labels

Abstract

The invention discloses a faceted search system and method based on water conservancy object classification labels. The system comprises a label module and a search module, wherein the label module is used for carrying out classification labeling processing on a metadata object in a water conservancy resource metadatabase and simultaneously managing the classification label in the system; and the search module is used for carrying out search query on metadata information according to a search request of a user and faceted selection. The faceted search system and method provides a "label" management function for a water conservancy information resource catalogue service system on the basis of the water conservancy information resource catalogue service system and carries out faceted search expansion on the simple search of the water conservancy information resource catalogue service system so as to lower the requirements of the user on knowledge in a relevant field, avoid the problem that user search gets lost and improve search efficiency.

Description

technical field [0001] The invention relates to a faceted retrieval system and method based on classification tags of water conservancy objects, belonging to the field of intelligent information retrieval. Background technique [0002] Traditional water conservancy field information search engines index the keywords in the data set. When users submit keyword query requests to the search engine, the search engine searches the database through keyword matching and feeds back the results to the user. This retrieval method requires users to have a high professional knowledge background, and the support for the general users is not high; and the user's retrieval intention is often not clear, what the user needs is an exploratory retrieval, and the system should carry out the user's retrieval. Guidance; keyword retrieval only uses keyword matching, and when there is no keyword matching, the search result will be empty, and the user experience is not good; the retrieval result is t...

AI Technical Summary

Problems solved by technology

However, most of the current faceted retrieval technologies only focus on the relationship between facets and facets, and seldom consider the relationship between facet values ​​and facets, while users of water conservancy business systems often pay more attention to facet values. cannot meet the needs of water conservancy business, therefore, in the field of water conservancy, there is an urgent need for a faceted retrieval method that can meet user business needs
